Application filed .Tune 10, 1924. .Ser'iaI No. 719,226.

The invention involved lherein relates toA the manufacture of bo'okcovers or other binders or articles of like character.

down to form a neat finish.

A characteristic example. is a book cover in which the covers or back orboth are rein-r forced by stiff cardboard over which is drawn theoutside finishing material such as leather7 fabric or paper. Y y

1n the finer grades of such book covers it is frequently desired `tohave round corners;`

Such corners have given a. great deal of difficulty in the coveringprocess and havev involved additional steps and additional eX- pense andfrequently imperfect work.

My present invention contemplates mechanism by which such covers can beformed in a single operation with great rapidity and great accuracy. Asillustrative of my invention I will show in the accompanying drawings anembodiment which I have 'found highly successful inpractical use.

Throughout the specification and drawings like`reference characters areemployed to indicate corresponding parts, and in the drawings Figs. 1and 2 are side and front elevations, respectively, of a press inaccordance with my invention.

Figs. 3 and t are end and side elevations of the forming members inseparated relation.

Fig. 11 is a fragmentary section showing the, adjusting blocks for the`suction plate.

Figs. 12 and 13 show in plan the positionings of the corner blades.

Fig. 14 is a side elevation, and

Such articles usually comprise a body portionbrl portions of thicker orstiffer vstock to which a sheet ofh covering material is attached,lthesame being drawn over the edges and folded y It 1s driven by the mainshaft' and pulleyj 6. A usual hand control y7is provided andy Fig. 15l asection through a corner blade, and i Figs. 16 and 17 are plan views ofthe rtwo' leaves of the corner blades. f

REGINALD ALVIN MCCAULEY, OF DORCHESTER, MASSACHUSETTS, 4ASSIGNOR T0.

Referring to F igs.y 1 and 2, I have-indicated at l the base, at 2 thehead7 and at 3 the reciprocating slide working in va way'li.l

Va foot pedal 8. A suction device 9 is conmember generally indicatedl as11 consists of al plate 111 havinga Vseriesof bladeoperating lingers 112which are for `the side blades and 113 which are the corneroperating'iinl. gers. All these lingers are lwedge shapedfas at'llQl or1131,-the`se wedging faces'aetingq being an oblong' body or sheet'withround'ed corners as above suggested. Referring to Fig. 5, it willbe seen that the top .plate la ofthe base is a rectangu-A lar "orquadrilateral piece having a central raperture of the size and shape ofthe partieularblank tobeoperated'on. The platesla .are removableandreplaceable vto accommo-v date Vcovers of dilferent siZes'or shapes andact as a gage in locating the blank in' the machine. The lower member121s a'bloek-shown in Fig. G as exposed bythe removal of the upper gageplate 14. It is recessed to a size'V preferably conforming tothe areaand shape of the blank tov be yoperated on and foi` thatv purposereceives a suctionplate 15. provided with'a hollow-stein 16 by which itis operated and througl'i which 'it Iis vented.' The stem 16 is operablyconnected to a yoke 17 which by links 18 can be raised or lowered byrthe vpedal 8.

The initial operation is illustrated 'in the sections shown in Figs. 7and 8,'the assembled blanks 'B and S glued or cemented together beingpositioned on the plate y111 over the suction plate 15. The exhaustvalve is then opened and the blanks B and S are drawn to and firmly heldby the perforated plate 15.

The foot lever 8 is then depressed and the plate lowered drawing theblanks B and S down so that the edges of the blank B are laterallyupturned as shown in Fig. 8, being turned up against the edges of thestiffening material VS.

At this point the hand lever 7 is thrown and the press begins to turnover lowering the plate 11. The lingers 112 and 113 now Y` entertheirrespective openings and engage the lateral blades 18 and corner blades19 to, effect the edge turning motion. These blades'are provided withrollers laand 19- tive movement, the slide 19 being slotted to .receivea pin 19b between kwhich and the Wall of the slot is connected a spring19C. This permits the slide 19 to move forward Vover the edge of thestiftening blank S as it turns the edge of the covering blank B oversaid stiening blank. Similar-bearing rolls 18b are provided in thelateral blades :tor 'contact with their operating lingers 112.

In initial positionfas shown in Fig. e, the combined blanks B and S areslipped `in while the plunger is raised so as to occupy the aperture ofthe gage plate 14 so as to be properly positioned. In this position itwill be noted .that the edges ofthe blanks B which are gaged on the.inner edges of this .aperture overlie the slides 18 while the main bodyof the blank rests Von the suction plate 15. At this point the valve 10is turned to its exhausting position and the plate 15 eX- haustedthrough its stem 10 thus drawing .the combined blanks firmly to itsupper surface. The treadle is now depressed lowering the plate 15 tojust below the level of the lateral blades 18. This turns up the marginof the blank B vertically so that it stands against the blades 18 withthe main body of the blank just below the lower edge of these blades.This position may be accurately adjusted by the wedges 2O which areadvanced or retracted by knnrled head screws 21 as appears in Figs. 9and 11.

tion shown in Fig. 6. The corner blades 19 are timed toadvance justafter the blades 18 come forward and draw up the material of the sheet Bat the corner.Y The blades 19 and 191 advance together, the blade 191being stopped by the resistance of the 'stiiffen-` ing blank `B andblade' 19 continues't'o ad vance aA distance represented by the turn.over of the leather 'orf other material being turned. Vxhen the bladesare all in their proper position, the plunger 11 has reached the bottomof its stroke and the platell1 which is the size of the finished blankpresses firmly down on all these blades thus pinching the coveringmaterial' firmly over they edge of the blank. The plunger; head now re--treats, the footV pedal is released to Vpermitv the rise of the suctionplate 15 to the -posi-V v tion shown yin Fig. 10 which is its initialposition. The airis reversed froniexhaust to pressure and the 'blankreleased (from the suction plate and removed so that the inachine isready for the next blank.

When it is desired to change the style or' size of cover to be made thehead o1'. the press is lowered bringing the plunger plate to its lowerposition and the two plates thenv release, one from its plunger andtheother from `the bed of the machine and are lifted out together Themachine can be loperated very rapidly and by unskilledlabor sothattheexperienced book binder vcan be replaced by unskilled help while atthe same time production is increased, and .more perfect work produced.y

Various modifications may be made in de- 1 tails of Vconstruction andoperation all without departing from the 'spiritof my invention ifwithin the limits of the appended claims. l
